The INV BS Series offers all the flow control features of the INV series however at a lower cost. It achieves this by only offering pump control from the panel, doesn’t feature dry run protection and the pumps are close coupled with extra fan cooling on the motors instead of a gear box.
It covers only the MINOR 40 & MAJOR 60 models and requires a 3 Phase power supply due to the 4 kW Frequency converter panel. There is a larger flow capacity available from the MINOR 40 due to the ability to operate the pump up to 1400 rpm. However the minimum speed is only 175 rpm for both models as opposed to 50 rpm for their INV counterparts.
Garolla fittings and SS304 Materials are fitted as standard with Natural Rubber Impellers. A Spring Loaded By-Pass is available for the MINOR 40 Model and a Manual By-Pass option is available for the MAJOR 60.
✓ Chemical (starch, water based glues, paints, ink)
✓ Cosmetic and pharmaceutical (liquid soap, shampoo, moisturiser, cleaning products)
Transferring Filling Emptying Recycling & Mixing
Filtering & Separation
Metering & Dosing
Operation Benefits:The vanes of the impeller deform slightly when rotating inside the pump casing, moving the fluid from the inlet to the outlet at a steady, pulseless flow without pressure spikes. This principle combined with a gentle pumping action and a high self-priming capability, up to 6 m from dry, makes these units ideal for transfer, filling, dosing and filtration applications.
1. Extremely good self-priming ability:
Up to 6 m from dry, enables the evacuation of sumps, tanks, drums & IBCs without the need for a non-return valve or manual priming on installation.
2. Reversible operation:
The pump can operate in both directions of rotation, which permits the return of excess liquid without any manual intervention, and also allows easy emptying of pipes on completion of the liquid transfer. This is particularly useful when emptying tanks for cleaning purposes and refilling afterwards at the flip of a switch.
3. Efficiency even at low operating speeds:
This allows the transfer of soft and fragile fluids with viscosities up to 50.000 cPs, or with solid particles in suspension, without causing air-locking, avoiding emulsifying or damaging particles. This makes these units ideally suited for shear sensitive fluids.
Impeller Features:✓ Natural rubber (NR): Excellent for water based liquid at room temperature, highest mechanical resistance.
✓ Neoprene (CR): Good balance between chemical and mechanical resistance.
✓ Nitrile (NBR): Excellent resistance to oils and fats.
✓ EPDM: Best for hot fluid and CIP cleaning. Excellent for acid and alkaline fluids.
✓ Silicon (VMQ): Best for high temperature but low mechanical resistance.
NOTE: All impellers are food grade however only EPDM & NBR are able to be supplied with FDA Certification.
Exploded View & Build Options:
4. The pump can work in all mounting positions:
The casing can be rotated through 5 different positions enabling the pump to be installed into various pipework configurations enabling the customer to make the pump work for their system and not alter the system to fit the pump.
5. Smooth steady pumping action of the product without pressure spikes:
Provides an even flow rate ideal for filling, dosing or filtration applications. The Midex and Minor pumps can be fitted with spring loaded by-passes to enable operation with nozzles or delivery valves to protect the pumps against “dead head” operation.
6. The easy mounting principle, the multiple choices of production materials provides a wide, versatile and customisable product range. Every pump range can be produced with different impeller types, sealing options, couplings / connections, numerous executions, with or without control panels and remote controls. A wide range of accessories are also available.

Impeller and Seal Compatibility are to be checked thoroughly against the impeller compatibility chart and suitability of SS304 & SS316 to be verified as well.
Performance Curves and Charts show DIFFERENTIAL head (H), therefore, pipe friction loss and suction lift need to be added to the discharge head.

2000cP: 470rpm Max
4000cP: 300rpm Max
For pumps being used on low and high viscosity fluids then 2 speed, mechanically variated or inverter driven pumps are recommended.
Spring Loaded By-Passes are only available for MIDEX and MINOR units therefore all other units need an external relief when being used with nozzles or on a system where closed valve operation is possible.
As these pumps are reversible, wiring and direction of rotation need to be monitored when installing and operating the pumps.
Viscosity affects the capacity and suction lift capability of pumps, for fluids with a viscosity of approximately 100 cP a 25% loss can be expected. For products with a viscosity of approx. 4000 cP, a 60% loss can be expected. This needs to be taken into account when selecting a suitable model. Furthermore, the operating speed of the pump should also be reviewed as well.

Features the Pony Plus 4 Liquid Measuring & Reading Instrument with timed intermittent output signal, connected to a variety of flow meters to provide real-time display of flow rate and total flow rate achieved. The desired quantity can be set to obtain an output signal (12 VDC 5A) controlled by a programmable timer. This enables a cost effective method of monitoring transfer applications as well as batching from larger bulk carrying tanks such as IBCs to smaller vessels. The output signal generated can be used to stop a pump or close a valve or signal a sounder beacon or light indicator.
The system can be supplied wired and configured for use with the following flow meters according to the line size and capacity range required. NOTE: Max Viscosity the flow meter can handle is 80-100 cPs.
The system can be supplied as a standalone portable kit for use with external pumps or valves, as shown to the left, or can be supplied as a bespoke system wired and piped to a suitable pump as a drop in solution, as shown in the below example, designed and calibrated to fit the application requirements.

To reduce packing and transportation charges the handle for the trolleys and the control panels are supplied loose and need mounting according to the following images. The top bracket for the control panel comes with a loop hook for hanging remote controls, if supplied.
If you are not mounting the control panel to a trolley handle then a 30 mm ø tube or pipe is required to enable it to fit into the moulded back of the panel. The groove is fitted with 2 strips of friction paper to assist with keeping the panel from slipping during mounting and operation.
Cable ties are supplied for tidying up cables between the panel and the motor. The panel comes pre-wired to the pump with a standard length sized for fitting the panel to the trolley handle therefore if you need an extended length of cable this needs to be pointed out at the enquiry stage.
1. Reversing switch - The reversing switch is available in a one or two speed configuration. The single speed version has pos. O for standstill mode, whilst the 1 and 2 positions represent the two rotational directions of operation.
The two speed version has two speed positions for each rotational direction:
Pos. 1 represents the lowest speed and pos. 2 the highest. Some pump executions with a single phase motor have a starting reverse switch; in this case the switch must be put on pos AVV and kept in this position until the pump comes into operation. The switch is then released which will automatically stop in pos. 1 or 2. This operation must be repeated each time the pump is started and also when reversing the rotational direction. Pumps with this starting position should not be used for automatic working (for example with level sensors).
With CE Compliant control panels there is a start button which needs to be pressed before each pump start up and every time the panel is connected to a power source in case of a voltage drop.

Lowest Speed Lowest Speed
Highest Speed Highest Speed

2. Dry run protection - The dry run protection device is connected directly to the pump body inthe form of a temperature sensor (1), which stops the pump when the internal temperature is higher than 50 °C, in order to avoid burning or deformation of the impeller.
The standard temperature sensor is not suitable for the transfer of liquids at a temperature higher than 45 °C. Higher temperature rated sensors are available on request (70ºC & 90ºC Rated) when the pump is required for transferring fluids above 45ºC.
Please note that the dry run protection device does not interrupt the passage of electric current. Therefore, once the temperature inside the pump body drops below 50ºC the pump will automatically start up again.
3. Frequency converter operation with remote control - The pump is directly operated through a remote control wired to the control panel via a 10 or 15 metre long cable. The remote features an On / Off / Reversing Switch (B) and a Speed Controller (A). The pump speed can be adjusted at will, even whilst the pump is running, according to the required capacity. Before using the remote control the main control panel must be switched on by turning the mains switch (C) from the position 0 to the position 1. The panel also has an additional, optional, dry run protection feature and 24V shunt (normally closed contact) which allows the connection of other devices such as pressure switches, level sensors, flow meters, remote controls, etc...
The Frequency Converter operating parameters are pre-programmed before supply and no other modifications are required. It is not recommended to use the small viewing panel (E) on the panel unit and any modifications to the parameters of Frequency Converter can result in improper operation of the pump and may invalidate the warranty.Please note that the pump will only work if the 24V Shunt is connected to the plug (F) or connected via an external device which closes the electrical circuit through the supplied connector (G).
4. Frequency converter with radio control - The pump is directly operated through a radio controller. After the pump has been switched on through the main switch, it is possible to control the pump directly from the main control panel or through the radio remote control (except the minimum speed restart function). The functions of the remote control are mirrored on the main control panel by the lighting of the corresponding buttons; for example, pushing the red stop button on the radio control, will turn on the red light button on the panel. The controller can be used effectively in a 100m radius of the apparatus.
MAINS SWITCH [A] – The mains switch turns the control panel On / Off and acts as an isolating switch. When the control panel is turned on, the frequency converter display [H] turns on as well and the pump is in the STOP position, indicated by the red button illuminating [B].
STOP BUTTON (RED) [B] – By pressing the STOP button the pump is stopped. On the control panel, the illumination of the STOP signal has 2 different functions:
Constant light if the stop command was given by the operator (stop until other command)
Flashing if the stop signal was given by an external signal, i.e. the radio controller (temporary stop related to the external signal).
LEFT ROTATION BUTTON [C] OR RIGHT ROTATION BUTTON [D] – These buttons control the left and right rotation of the pump (on the control panel the corresponding button will light). On the control panel the illumination of the right and left buttons has different meanings:
Constant light shows the pump is running in the set direction
Flashing light shows the pump has been stopped by the operator, this illumination is intended to indicate the rotation before the STOP of the pump.
It is possible to reverse the direction of rotation of the pump even whilst the motor is running. The changeover will be made according to the acceleration / deceleration set in the frequency converter (these values vary depending on the model of the pump).
INCREASE [E] OR DECREASE [F] BUTTONS – These buttons increase or decrease the rotational speed whilst the pump is running (on the control panel the corresponding button will light up). The speed will vary proportionally; with a short press you will have little variation, with a long press will have a linear variation up to the minimum / maximum value set (the minimum / maximum values vary in relationship to the model of pump).
MINIMUM SPEED RE-START SELECTOR [G] – Set to ON: the Minimum restart function is activated, after the pump has been STOPPED by the user, it restarts at the minimum speed.
Set to OFF: the Minimum restart function is disabled, after the pump has been STOPPED by the user, it restarts at the speed achieved before the STOP.
Attention: This setting only works when the user stops the pump. If an external source stops the pump (ex. thermal sensor or other) it will restart at the speed set before the stop.
